Using the method `debug_struct()` of `fmt::Formatter` takes care of
the exact formatting for us. Additionally, it also handles the
"alternate" form of printing enabled with '#'. In the struct case it
prints the struct on multiple lines instead of just one.
This commit also changes the output slightly. Before, the field
`log_level` was printed with `log: {}`. This commit replaces "log"
with "log_level". Additionally, the value of `environment` is now
printed as a struct field instead of being combined with the struct
name.
Prior to this commit, relative paths to TLS PEM files were incorrectly
treated as being relative to the CWD as opposed to the Rocket config
file, when present. This commit resolves the issue.
The latest version of `rustls` acts on the SNI extension to TLS without
the apparent ability to disable the behavior. `rustls` requires that the
server's certificate match the client's requested server. The matching
is done by looking at DNS names in the `subjectAltName` extension and
checking if the requested server name is present. Since the certificate
in the `tls` example did not have the `subjectAltName` extension, this
check always failed, and the TLS connection was aborted. This commit
adds the extension to the certificate with a DNS name of `localhost`,
ensuring that TLS succeeds on `localhost`.
Prior to this commit, a 'json!' invocation returned a value of type
'Value' from 'serde_json'. Because 'Value' does not implement
'Responder', most uses of 'json!' were wrapped in 'Json':
'Json(json!(..))`. By returning a crate-local 'JsonValue' type that
implements 'Responder', this repetition is resolved, and a 'json!' can
appear unwrapped.
This commit also removes the reexport of 'Value' from 'rocket_contrib'
as well as the default type of 'Value' for 'T' in 'Json<T>'.
This commit modifies `codegen` so that a route's name (the name of the
route handler) is stored in the generated static route information
structure and later propogated into the corresponding `Route`
structure.
The primary advantage of this change is an improvement to debug and
error messages which now include route names. The collision error
message, in particular, has been improved dramatically in this commit.
Additionally, the `LaunchError::Collision` variant now contains a
vector of the colliding routes.
Rust's linting API is incredibly unstable, resulting in unnecessary
breakage to `rocket_codegen`. Rocket's lints are also not as
conservative as would be desired, resulting in spurious warnings. For
these reasons, this commit removes linting from `rocket_codegen`.
These lints will likely be reintroduced as part of a 'rocket_lints'
crate. Factoring the lints out to a separate crate means that lint
breakage can be dealt with by uncommenting the dependency instead of
waiting for a new release or backtracking nightlies. In the same vein,
it will likely improve stability of the 'rocket_codegen' crate.
The first line in the Tera error messages is sometimes less useful,
but in other cases, like when the context is not a map or struct,
contains the complete description. As such, always include it, even if
the output is slightly uglier. Also don't append periods at the end
since some Tera messages already have them.
